issue confirmed

This is not a com_media issue.

opps hit enter too soon.

The problem is with the CMS Filesystem Library.

ыыыыыыыы is passed to File::makeSafe

But that returns an empty string.

This in turn in com_media is resolved to /path/to/images which it then silently tries to great, but obviously its already there.

Here is the isolated code: https://3v4l.org/Aj8Ef

As you can see it works fine there, so the question is - for you have the iconv PHP Extension installed?

yes

and for transliterator_transliterate how about the Intl Extension ?

So that's the problem then, Your platform doesn't have ICONV and INTL PHP extension as needed by File::makeSafe in order to transliterate the text to a safe useable folder name of yyyyyyyyy

PR #33451 to provide better messaging

confirming that enabling both extensions does result in a folder being created
